How to display resources for WatchGuard firebox firewall?

sorry for the double post. I posted in the Firewall Analyser by mistake earlier. This is about OpManager.

We have a WatchGuard Firebox 500 firewall but we don't see the CPU and Memory Utilization in OpManager. We are able to see the network interface and Rx traffic but not much else. I have the MIBs for Firebox but not sure how to use it. I am using the OpManager web interface. I am new to this. I have enclosed a screen shot.
